Our research is at the intersection of quantum information science, quantum optics, and condensed matter physics. We build devices that combine superconducting circuits and microwave cavities and explore their quantum properties at milliKelvin temperatures.

Welcome to the Chakram lab @Rutgers!

The past three decades have witnessed the renaissance of experimental quantum science, leading to the realization of a variety of novel engineered quantum mechanical systems with increasing coherence and control. These quantum systems include ultracold atomic gases, trapped ions, mechanical resonators, defect centers in crystals, optical photons, and superconducting circuits, and promise the dawn of a new era where quantum mechanics can be harnessed for advances in computing, simulating quantum materials, communication, sensing, and more.

Our group builds new superconducting quantum information processors that combine superconducting circuits with high-Q microwave cavities. Our microwave cavities are typically multimodal, possessing tens of modes with photon lifetimes of a few milliseconds. These cavities are combined with superconducting circuits to form multimode cavity QED systems with extremely high cooperativities. We plan to develop new hardware and explore schemes for quantum control, and error correction in these systems. These systems are also promising for exploring a new regime of many-body quantum optics, allowing the prospect of building exotic quantum materials using microwave light.
